IMPROVEMENT IN CULTIVATORS.

Specication forming part of Letters Patent No. 182,953, dated October 3,1876; application filed September 14, 1876.

To all whom -t may concern:

Be it known that I, J OBN PALGER, of El Dorado, in the county of Fayetteand State of Iowa, have invented certain new and useful Improvements inGultivators, of which the following is a specification:

This invention relates to certainimprovements in double or straddle7 rowcultivators; and it consists in providing the supportingframe of acultivator .with a shaft passing transversely through the central barsof the frame, serving as a point of attachment for the plow-beams, whichare provided with ears at their front ends, attached to the sides of thebeams, and provided with elongated slots for the passage of thesupporting-rod, said slots permitting the necessary play of the beamslaterally and longitudinally, in combination with an eye-rod extendingfrom the front transverse bar of the supporting-frame, and provided withcollars to prevent too great a lateral movement of the plowbeams, asmore fully hereinafter set forth.

In the accompanying drawing, Figure l is a perspective view of a doubleculti vator constructed according to my invention. Fig. 2 is a plan viewof the same. Fig. 3 is a detail view, illustrating the manner of fittingthe shovels so as to give the same an inclination.

The supporting-frame of the cultivator is composed of the front and reartransverse bars'A B and central longitudinal bars G, between the frontends of which is secured the draft-pole D. A rod or shaft, E, passestransversely through the bars C and pole, and terminates at the properdistance from the latter, so as to serve as the point of attachment fora pair of plow-beams, F G. The rod E is properly braced by means of thestays H extending from said rod to the rear transverse bar B, to whichthey are attached. The plowbeams are provided at their front ends withplates or ears I, which are attached to the sides of the beams, andprovided with elongated openings or slots J, for the passage of thesupportingrod E. Said slots will permit the necessary play of the beamslaterally and longitudinally. An eye-rod, K, extends downward from thebar A, and enciroles the rod E between the ears of the plow-beams.Washers or sleeves a are placed on the rod E, be-

tween the eye of the rod K and the ears of the beam. The eye-rods K, onefor each beam and the Washers, will not permit a too great lateralmovement of the plow -beams, while not preventing the play necessary tocultivate at a greater or less distance from the plants, or to avoidobstructions. The upper end of the eye rod or bolt K is threaded toreceive a nut, which attaches it to the bar A, said bar being providedwith several holes for receiving said eye-rod. rIo each beam areattached two shovel or plow standards, L M, which are set one in advanceof the other, and on opposite sides of the beam. The standards aresustained by means of braces N, which extend from the standards, and areattached to the beams by bolts or pins. The braces are provided With aseries of holes, so that the standards can be adjusted to give themdii'erent degrees of inclination.

The attachment ofthe rear end of the brace to the standard may beeffected by a xed pin or bolt, or a wooden pin may be used, which willbreak when the shovel strikes an obstruction, thus permitting thestandard to yield in a backward direction.

Each beam carries a handle, T, which is grasped by the plowman, for thepurpose of guiding the cultivator and adjusting the beams. The rear endsof the beams rest under the cross-bar B, and they are free to movethereon by properly manipulating the handles.. The beams may be heldupon the crossbar by a temporary fastening device; but this is hardlyever done, as it is desirable to have the beams capable of beingadjusted or shifted in nearly every instance of the use of thecultivator. The two inner shovel-standards may also be connected by abar, adjustable or fixed so as to have both beams move in unison witheach other but the independent arrangement ofthe beams is deemedpreferable.

The shovels used may be of any desired form, according to the kind ofwork to be done; but I generally employ the common pointed shovels l),which are attached in any suitable manner to the standards. In certaininstances it is essential that the shovels should be inclined to theright or left for throwing the earth correspondingly, and for permittingthis to be done in a simple and convenient manner I interpose aWedge-shaped block, Q, between the standard and the shovel, as is shownin Fig. 3 of the drawing. The draft can be applied directly to theplow-beams by attaching` whifdetrees to the front ends thereof, as isshown by the dotted lines in Fig. 1.

For convenience of attachment of the whifctrees I apply to the bottom ofeach beam a slotted plate or clevis, R. The whifdetrees may, however, beattached to the pole in the usual manner.

What I claim, and desire to secure by Letters Patent, is-

The combination, with the front and rear transverse bars A B, centralbars C between the same, the shaft E, passing transversely through thesaid bars, and the pendent eyerod K, having collars, as described, ofthe independent adjustable plow-beams F and G,
